On-board diagnostics OBD is an automotive term referring to a vehicle’s self-diagnostic and reporting capability.

OBD systems give the vehicle owner or repair technician access to the status of the various vehicle subsystems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early s versions of on-board vehicle computers. Early versions of OBD would simply illuminate a malfunction indicator light or ” idiot light ” if a problem was detected but would not provide any information as to the nature of the problem.

Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codesor DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle.

There’s an appearance of standardization because the diagnostic jack didn’t change over the years ALDL was utilized by GM.

GM North America used a proprietary 12 position Metripack diagnostic jack. GM Australia Holden used a 6 position Metripack diagnostic jack. It was actually extremely fragmented.

A PCM integrates transmission and engine control on one Processing unit. 15031- levels in the same model year, division, and nameplate can use different communications. It was not used on non-California emissions vehicles. 15013-5 small number of vehicles manufactured before from other manufacturers used the GM Lso Electronics engine and powertrain controllers; however, these used a modified ALDL communication protocol. Most did not and there was not a homogeneous name for these other proprietary diagnostic protocols and interface ports.

A and later California standard. It is not a USA Federal standard. By connecting certain pins of the diagnostic connector, the ‘Check Engine’ light will blink isp a two-digit number that corresponds izo a specific error condition.

Cadillac gasoline fuel-injected vehicles are equipped with actual on-board diagnostics, providing trouble codes, actuator tests and sensor data through the new digital Electronic Climate Izo display. Holding down ‘Off’ and ‘Warmer’ for several seconds activates the diagnostic mode without the need for an external scan tool. GM did not use the term OBD 1. For example, the 94—95 Corvettes have one post-catalyst oxygen sensor although they have two catalytic convertersand have a subset of the OBD-II codes implemented.

While OBD II interfaces will not communicate with these controllers they will not be damaged by plugging into these jacks either. Additional vehicle-specific diagnostic and control circuits are also available on this connector. For instance, on the Corvette there are interfaces for the Class 2 serial data stream from the PCM, the CCM diagnostic terminal, the radio data stream, the airbag system, the selective ride control system, the low tire pressure warning system, and the passive keyless entry system.

Flash codes can be retrieved on — Corvettes by shorting Vendor Option to 4 Chassis Ground. The OBD-II standard specifies the type of diagnostic connector and its 150311-5, the electrical signalling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each. There is a pin in the connector that ios power for the scan tool from the vehicle battery, which eliminates the need to connect a scan tool to a power source separately.

However, some technicians might still connect the scan tool to an auxiliary power source to protect data in the unusual event that a vehicle experiences a loss of electrical power due to a malfunction.

As a result of this standardization, a single device can query the on-board computer s for these parameters in any vehicle. OBD-II kso was prompted to simplify diagnosis of increasingly complicated emissions equipment, and though only emission-related codes and data are required to be transmitted through it according to U.

P for engine and transmission powertrainB for body, C for chassis, and U for network. Manufacturers may also add custom uso parameters to their specific OBD-II implementation, including real-time data requests as well as trouble codes.

Both are female, pin 2x8D-shaped connectors, and both have a groove between the two rows of pins, but type B’s groove is interrupted in the middle. This prevents the insertion of a type A male plug into a type B female socket while allowing a type B male plug to be inserted into a type A female socket. The type A connector is used for vehicles that use 12V supply voltage, whereas type B is used for 24V vehicles and it is required to mark the front of the D-shaped area in blue color.

Inall previous standards were revoked because there were more than 24 standards 150311-5 over 35 years. The new document supplanted all previous versions. Each of the EOBD fault codes consists of five characters: The letter refers to the system being interrogated e. Pxxxx would refer to the powertrain system. The next character would be a 0 if complies to the EOBD standard.

So it should look like P0xxx. The following two characters would refer to the individual fault within each subsystem. It is often possible to deduce the protocol, based on which pins are present on the J connector:.

All OBD-II pinouts use the same connector, but different pins are used with the exception of pin 4 battery ground and pin 16 battery positive. OBD-II provides access to data from the engine control unit ECU and offers a valuable source of information when troubleshooting problems inside a vehicle. The SAE J standard defines a method for requesting various diagnostic data and a list of standard parameters that might be available from the ECU. The various parameters that are available are addressed by “parameter identification numbers” parameter IDs or PIDs which are defined in J Manufacturers are not required to implement all PIDs listed in J and they are allowed to include proprietary PIDs that are not listed.

These range from simple generic consumer level tools to highly sophisticated OEM dealership tools ido vehicle telematic devices.

A number of new devices allow the vehicle’s OBD port to stream data directly to the Internet via a cellular connection. The software then decodes the received data to a visual display.

The extent kso a PC tool may access manufacturer or vehicle-specific ECU diagnostics varies between software products as it does between hand-held scanners.

Data loggers are designed to capture vehicle data while the vehicle is in normal operation, for later analysis. Analysis 150315- vehicle black box data may be performed on a periodic basis, automatically transmitted wirelessly to a third party or retrieved for forensic analysis after an event such as an accident, traffic infringement or mechanical fault.

Since OBD-II stores trouble codes for emissions equipment, the testing computer can query the vehicle’s onboard computer and verify there are no emission related trouble codes and that the vehicle is in compliance with emission standards for the model year it was manufactured. Driver’s supplementary vehicle instrumentation is installed in a vehicle in addition to that provided by the vehicle manufacturer and intended for display to the driver during normal operation.

This is opposed to scanners used primarily for active fault 15031- tuning, or hidden data logging. Auto enthusiasts have traditionally installed additional gauges such as manifold vacuum, battery current etc.

The OBD standard interface has enabled a new generation of enthusiast instrumentation accessing isl full range of vehicle data used for diagnostics, and derived data such as instantaneous fuel economy. Instrumentation may take the form of dedicated trip computerscarputer or interfaces to PDAs[30] smartphones, or a GPS navigation unit.

As 150031-5 carputer is essentially a PC, the same software could be loaded as for PC-based scan tools and vice versa, so the distinction is only in the reason for use of the software. OBD II is no longer only used by professionals and hobbyists to repair vehicles.

OBD II information is commonly used by vehicle telematics devices that perform fleet tracking uso, monitor fuel efficiency, prevent unsafe driving, as well as for remote diagnostics and by pay-as-you-drive insurance.

Although originally not intended 51031-5 the above purposes, commonly supported OBD II data such as vehicle speed, RPMand fuel level allow GPS -based fleet tracking devices to monitor vehicle idling times, speeding, and over-revving. By monitoring OBD II DTCs a company can know immediately if one of its vehicles has an engine problem and by interpreting the code the nature of the problem.

OBD II is also monitored to block mobile phones when driving and to record trip data for insurance purposes. SinceTitle 13 of the California Code of Regulations Researchers at the University of Washington and University of California examined the security around OBD, and found that they were able to gain control over many vehicle components via the interface. Furthermore, they were able to upload new firmware into the engine control units.

Their conclusion is that vehicle embedded systems are not designed with security in mind. There have been reports of thieves using specialist OBD reprogramming devices to enable them to steal cars without the use of a key.
